Answer 2

1 find the file that supports the spyware. (go to your start menu and go to "search". do a search on the name of suspected spyware.)

2 delete it, it'll probably have an error message, if it does then go to the task manager ( ctrl, alt, del) and go to processes find the suspected spyware and end process.

3 go back to the file and delete it. it should go away with no problem.

If that doesn't work then use an antispyware software.

This method is only tested on Windows 2000/XP/2003/NT. But have some difference on Windows 9x/ME, you may also use Twister Anti-TrojanVirus to remove it on Windows 9x/ME.

Step 1: Configure Microsoft Windows Explorer to show all files, because most Virus and Trojan horse can hide itself. If you already did it, you may skip this step.

   1. Click Start, point to Settings, and Control Panel, and then click Folder Options.

   2. In the Folder Options dialog box, click the View tab.

   3. In the Advanced settings box, deselect the Hide protected operating system files (Recommended).

   4. Select the Show hidden files and folders.

   5. Deselect the Hide file extensions for unknown file types.

   6. Click OK to save changes.

Step 2: Press Ctrl+Alt+Del, open Task Manager program, click Processes tab, find msstart.exe process, if found, select it and click End Process to kill it.

Step 3: Go to the folder of SystemRoot\Winnt\System32 (If your Windows NT/2000/XP/2003 installed on driver C: then the folder is C:\Winnt\System32), find msstart.exe and directly delete it. Or you can also search for all of msstart.exe files by using Windows Search feature (WINDOWS+F shortcut key), and delete them all.

At the end of the instructions, if all of the steps are completed correctly, then the Trojan has already been completely removed.
